How the number is built
Elo inputs in rating points (higher favors that team; 25–28 Elo is about a point of spread in football and basketball), then how the pieces combine.
| Factor | SEA | DET | Why |
|---|---|---|---|
| Team rating | 1525 | 1485 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −10 | −10 | SEA: Luis Castillo: team allows 0.49 more runs than with its usual starter (≈10 weighted starts) · DET: Jack Flaherty: team allows 0.50 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | SEA +23 Elo | SEA 53.3% | |
| Market-implied ratings | SEA 51.0% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SEA 51.3% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | DET 52.7% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
